Non visible custom controls

[Guest]

Does any one know how to create a control(like the timer) that when dragged
to a form doesn't show up on the form, but only on the bar in the design
window below the form?

Thanks
Ryan

Just derive your object from "System.ComponentModel.Component". The simplest
way is to right-click your project or some project folder in Solution
Explorer, then click "Add" followed by "Component...". You can subsequently
add this to the "Toolbox" and drag it onto any design surface (usually a
form). It will then appear in the design tray (the "bar" you referred to).

Ryan,

You will have to implement the IComponent interface. There is a base
implementation in the System.ComponentModel namespace named Component.
